1. What is Foot to PSI Conversion?

Definition: This calculator converts height of water column in feet to pressure in pounds per square inch (psi).

Purpose: It helps engineers, plumbers, and technicians working with fluid systems to quickly convert between these common units of pressure measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Pressure in pounds per square inch (psi)
• \( h \) — Height of water column in feet (ft)
• 2.31 — Conversion factor (1 psi = 2.31 ft of water head)

Explanation: The height in feet is divided by 2.31 to convert it to equivalent pressure in psi.

3. Importance of Foot to PSI Conversion

Details: This conversion is essential in hydraulic systems, water supply networks, and any application where water pressure needs to be measured or calculated.

4. Using the Calculator

Tips: Simply enter the height of water column in feet. The calculator will automatically compute the equivalent pressure in psi.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 2.31?
A: This comes from the relationship between pressure and water head: 1 psi = 2.31 feet of water column at standard conditions.

Q2: Does this work for other liquids besides water?
A: No, this specific conversion is for water. Other liquids would require different conversion factors based on their specific gravity.

Q3: How accurate is this conversion?
A: It's accurate for water at standard conditions (60°F). Temperature variations can cause slight changes in density.

Q4: Can I use this for very high pressures?
A: Yes, the linear relationship holds true regardless of pressure magnitude for water columns.

Q5: What's the reverse conversion (psi to feet)?
A: Simply multiply psi by 2.31 to get feet of water column.
